Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV001290567 SCV001478643 uncertain significance not specified 2021-01-25 criteria provided, single submitter clinical testing Variant summary: SPINK1 c.-14G>A is located in the untranslated mRNA region upstream of the initiation codon. The variant allele was found at a frequency of 4.4e-05 in 249980 control chromosomes (gnomAD). This frequency is not significantly higher than expected for a pathogenic variant in SPINK1 causing Chronic Pancreatitis Risk (4.4e-05 vs 0.005), allowing no conclusion about variant significance. c.-14G>A has been reported in the literature in at least an individual affected with Alcoholic Chronic Pancreatitis (Hegyi_2016). This report however, does not provide unequivocal conclusions about association of the variant with Chronic Pancreatitis Risk. In functional lucifierase assays, the variant was found to have varying activities (compared to wild type) depending on cell type (Hegyi_2016, Derikx_2015). Therefore, these results were not conclusive. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as uncertain significance.
